Challenge Token

Definitions

1. A short-lived token used to prove that a client is responding to a legitimate challenge or participating in a valid interaction. Challenge tokens appear in anti-CSRF defenses, proof-of-work systems, and other validation flows.

   In plain English: A temporary token used to prove a request or response is part of a valid challenge flow.

   Example: "The form required a challenge token so attackers could not replay a stale submission blindly."
